BENJAMIN C. MARSHALL, OF FORT WORTH, TEXAS.

COTTON-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 374,610, dated December 13, 1887.

Application filed September 15, 1887. Serial No. 249,763. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN O. MARSHALL, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Cotton-Choppers; and I do declare-the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

In the accompanying drawings, Figure 1 is a side elevation of my improved cotton-chopper with parts broken'away. Fig. 2 is aplan view of the same, and Fig. 3 is a detail more particularly hereinafter referred to.

My invention has reference to that class 0 devices which are designated as cottonchoppers, and it has for its object to produce a device of this class which shall possess superior advantages in point of simplicity, durability, ease of operation and manipulatiomand general efficiency. v

To these ends and to such others as theinvention may relate the same consists in the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then specifically defined in the claim.

Reference being had to the details of the accompanying drawings, A designates the main frame of the machine, which is preferably of iron, and is provided with bearings B for the transverse axle O, carrying upon its outer ends the wheels D D. The axle G is made laterally adjustable by means of the adj ustable j ournalboxes 0 for a purpose hereinafter described, and is provided with an adjustable gearwheel, E.

At a point near the rear end of the frame of the machine is journaled in suitable bearings the transverse shaft G, provided at intervals of its length with gear-wheels G of different diameters. The shaft is also provided at a point near its longitudinal center with a beveled gear-wheel, G

To the rear end of the frame A is hinged the skeleton arm or cylinder F, within which is journaled the shaft F, which is rotated by means of the engagement of the beveled pinion F secured to its end with the beveled gear-wheel G The shaft F is bent downward at a point near its rear end, as shown at H, and to its lower end is adjustably'secured the hoeblade H I I are braces secured at thcir upper ends to the handles of the machine, and made adjustable, as shown. It will be readily understood that by adjusting these brace-rods the angle of the shaft F may be regulated at will.

J is a clutch attachment, whlch may be of any approved and suitable construction, and it is operated by means of the rod J the handle of which is preferably placed between the handles of the machine, and thus convenient to operate. I

It will be readily understood that by a sim' ple manipulation of the rod J the pinion F will be thrown either into or out of gear or engagement with the gear wheel upon the shaft G, and that the rotary movement of the hoe-shaft will be thus controlled. Motion is communicated to the shaft G from the axle G by means of the engagement of the gear-wheel E with one of the gear-wheels G upon the shaft G. I

From the foregoing description it will be understood that the angle of the hoe-shaft can be regulated at will, so as to accommodate the machine to the character of the work to be done. The hoe-blade may be readily removed or changed, and if for any reason it should be thought advisable two or. more hoe blades may be attached to the shaft F, as shown in Fig. 3 of the drawings. The momentum of theshaft G may be regulated by adjusting the gear-wheel so as to cause the same to engage with one of the gear-wheels G they having which has been displaced without covering the allel with the axle, a plurality of gear-wheels plants in the adjacent row, which is a fault of varying diameters on said shaft,a bevelcommon to many of the cotton-choppers herepinion also on said shaft, and an inclined shaft I 5 tofore used. carrying the hoe and provided with a bevel- 5 Havingthus described myinvention and set pinion engaging the pinion on the shaft G,
